One thing that you need to keep in mind when building regexes like these is the subject of greedy.   By default, the regex will (“greedily ...”) find the longest available string that matches.   You can specify that it should, instead, opt for the shortest one, and sometimes (depending on the nature of the string that is to be processed) you must do that.

I also strongly advocate that your programming should be suspicious of its input files.   If you expect 5 strings, check each time that you have them.   In short, if you can be certain of anything in the correctly-running program given correct data, “be from MIssouri ... show me.”   Quite frankly, most of the time, I’ve encountered broken data.   The supplier of the data didn’t know it was broken.   “Inexplicable bugs” turned out to be from that cause.   Only the computer itself is in the necessary position to recognize the existence of these issues ... take the slight extra time to make it do so.

    [ambrus]: it now has two more people working there, and they're serving slower and more expensive.
    [ambrus]: It used to be just a master cook who takes the order and puts the meat and eggs on the open grill plate table, and an assistant who removes them to a plate, adds the side dish, and gives the plate to the people in the queue, plus a cashier.
    [ambrus]: Now it has five people instead of three, some sort of call number ticket system where people wait a lot for their food to get ready (it's the same kinds of grilled meat and fish on the same equipment, it won't actually fry slower),
    [ambrus]: it's slow as hell, and the food costs significantly more.
    [ambrus]: We no longer eat there.
    LanX Everybody quotes it, some people read it, and a few people go by it
    [ambrus]: LanX: why would I read it? isn't it a book for managers? I don't want to be a manager.
    [ambrus]: I don't quote it either.
    [erix]: it's really a software book, albeit about experiences from the 60s-80s. People haven't changed all that much though.
    [erix]: a software project book, is probably more exact
